Fine rain and a breeze (3)
I believe the answer is:
air
'a breeze' is the definition.
('air' can be a synonym of 'breeze')
'fine rain' is the wordplay.
'fine' becomes 'ai' (resembles Ar, informal term for top quality).
'rain' becomes 'r' (this might be a standard abbreviation which I don't know about).
'ai'+'r'='AIR'
'and' is the link.
Can you help me to learn more?
(Other definitions for air that I've seen before include "Publish" , "Atmosphere (of a melody?)" , "Mixture of gases required for breathing" , "strain" , "Mix of gases surrounding the earth" .)
